CAN Datalogger


Connect any CAN bus enabled device and record the raw CAN frames in a non-volatile memory!

CAN datalogger is a compact, standalone device that can acquire the raw CAN bus frames from a vehicle or any industrial device and record them in internal storage. The device can be configured quickly using the customized tool PreciCON and records any CAN bus protocol independently (such as J1939, OBD2, CANOpen, NMEA etc). Once recorded, the log files can be downloaded in industry standard .CSV or .MF4 format using the same tool.

This device is best suited for specialized use cases, such as J1939 datalogger, OBD2 datalogger, etc offering reliable performance and ease of integration. Its user-friendly interface allows for easy configuration and data retrieval, making it a valuable tool for monitoring and analyzing CAN bus communication.

Applications

J1939 Datalogger in Heavy duty vehicle

The J1939 protocol is widely used in the commercial vehicles (e.g., trucks, buses, construction equipment, and agricultural machinery) for many applications such as fleet management, on-board diagnostics, etc where an aftermarket CAN datalogger is essential.
Our CAN datalogger can easily connect with heavy vehicle CAN bus and can operate as a J1939 data logger enabling fleet management with no extra monthly charges using an out-of-box PreciCon software. It allows real-time monitoring and logging of engine parameters, vehicle speed, fuel consumption, and fault codes directly from the CAN bus. The compact design and plug-and-play setup make it ideal for both fleet operators and service engineers. With easy data export and analysis features, it simplifies maintenance planning and enhances operational efficiency.
